DISCOVERING PATTERNS OF INSURGENCY VIA SPATIO-TEMPORAL DATA MINING James P.Rogers¹, James A.Shine¹, Shashi Shekhar², Mete Celik² ¹U.S. Army ERDC, Topographic Engineering Center, VA, USA {james.p.rogers.II, james.a.shine}@erdc.uasce.army.mil ²Department of Computer Science, University of Minnesota, MN, USA {shekhar,mcelik}@cs.umn.edu Abstract Experimental Evaluation The need to discover patterns in spatio-temporal (ST) data has driven much recent research in ST co-occurrence patterns. Early work focused on spatial patterns such as co-location ignoring the temporal aspects of ST datasets. This work describes a novel set of co-occurrence patterns called mixed-drove co-occurrence patterns (MDCOPs). They represent subsets of two or more different ST object types whose instance are close to each other spatially and temporally.

The crystal is made of either silicon or germanium. This is the same material from which transistors and solar cells are made. The sensors employ state-of-the-art superconducting technology fabricated in a manner similar to computer chips. The sensors on the crystal surface give two sets of signals each time a particle interacts with the crystal: [1]Vibration: An array of tiny sensors on one side detect vibrations in the crystal produced by an incoming particle. A tiny vibration in a crystal is called a “phonon”. [2]Charge: A metal grid on the other side collects electronic charge which was displaced within the crystal by the incoming particle. The detectors are assembled into “towers”. One tower has 6 detectors. The towers are inserted into the “icebox”, which is really much colder than ice! In fact, the detectors work best at only 0.02 degrees above absolute zero, the temperature where all random thermal motion stops. DARK MATTER: One of the greatest mysteries in the history of cosmology! Cosmic rays are blocked by the earth above the experiment. WIMP CRYOGENIC DARK MATTER SEARCH: DETECTING WIMPs IN THE CDMS EXPERIMENT Most recent picture of fridge. CDMS currently operates a complementary experiment at Stanford University at the Stanford Underground Facility. It has produced the strongest limits yet on WIMP interactions with matter. But, operating in Soudan will dramatically increase our sensitivity! photons (light...

Teacher-Student Relationships Literature Review - African-American students learn from direct contact with teachers and peers, taking a holistic relational, and intuitive stance. Teachers of African American students have to be more than effective teachers. Instead, they must also be “culturally responsive teachers who contextualize teaching by giving attention to immediate needs and cultural experiences of their students.” (Irvine, 1992, p.82) Expert interviews – Set them up as leaders in the class room. “If you will try, you will pass.” Student interviews - Examples of good and bad teacher student relationships. She asks a lot of questions, teachers laugh and ask “Why would you ask that?” They don’t like that, It’s frustrating for them. Wishes teachers would consider everyone and make sure they understood, instead of moving on. Preferences for Learning Math Literature Review - Mathematical Literacy – An individual’s capacity to identify and understand the role that mathematics plays in the world, to make well-founded judgments, and to use and engage with mathematics in ways that meet the needs of that individual’s life as a constructive, concerned and reflective citizen. [OECD's Program for International Student Assessment (PISA, 2000)] “African American students usually learn in ways which are characterized by social and affective emphases, harmony with the community, holistic perspectives, field independence, expressive creativity, and nonverbal communicat...

Recent developments in synthesis and characterization of incompatible polymer blends are motivated by environmental sustainability. The quality of the blend is sensitive to its microstructure and influences end-use properties. The microstructure is generated during processing. We implement a numerical algorithm for the simulation of the motion of a droplet governed by the Oldroyd-B constitutive model or, when a quadratic stress tensor is included in the equations, the Giesekus constitutive model. A droplet suspended in a matrix liquid and sheared between parallel walls is simulated in 3D. Governing equations are the incompressible Navier-Stokes equation, The numerical results are compared with experimental data at large deformation, for a Boger fluid drop in a Newtonian matrix. De_d = 1.54. Viscosity ratio 1.5. The drop is more retracted with increased shear rate because the viscoelastic stress at the drop tips act pull the drop in. A computational study of mixing incompatible polymers for recycling plastics: a sustainable future Matrix phase dispersed phase coupled with a viscoelastic constitutive equation (Giesekus model), Relaxation time Solvent viscosity Surface tension Giesekus model parameter Polymer viscosity The steady shear rheological data of a Boger fluid at 25C show that the viscosity and first normal stress coefficient are constants. A Giesekus model is used for higher strain rates. Capillary number Cahm’a/ , viscous/capilla...

On the Origin of Vorticity Banding : experiments on fd-virus suspensions K. Kang, M.P. Lettinga, J. K. G. Dhont (Research Centre Juelich, Germany) Suspensions of very long and thin colloidal rods (fd-virus particles) exhibit vorticity banding within part of the paranematic-nematic coexistence region. Inhomogeneities that are formed after a shear-rate quench are shown to be responsible for vorticity-banding. Particle-tracking experiments reveal that there is rolling flow within the bands. This lead us to propose that vorticity banding is an elastic instability, where the shear-induced non-linear, elastic deformation of the inhomogeneities generate hoop stresses, similar to the Weissenberg effect for polymers, where now the role of polymer chains is played by the inhomogeneities [1,2,3]. 23 % : 35 % : spinodal decomposition nucleation and growth Binodal 0.0 0.5 1.0 0 2 Spinodals Tumbling wagging Critical point Vorticity banding nem The phase diagram : Fd virus : Length : 880 nm Thickness : 7 nm Persistence length : 3000nm bands are in internal rolling flow Particle tracking : polymer chain (Weissenberg effect) non-linear elastic deformation of inhomogeneities Growth kinetics : H 0 band width growth time 1 2 3 4 5 6 7 8 A stretching of inhomogeneiti...
